You will learn to diagnose all of the common faults conditions with rolling element and sleeve bearing machines, by utilizing time waveforms, phase readings and other techniques to diagnose faults. You will also learn machine dynamics (natural frequencies, resonance, etc.) and how to perform resonance testing and correct resonance problems. The course also covers single and cross-channel measurement capabilities of your analyzer. And after completing the CAT-III course, you will be able to set and run a successful vibration program, and mentor the junior analysts.

Mobius vibration analysis training is unique. We use 3D animations, Flash simulations, and numerous software simulators that completely demystify vibration analysis. While vibration training courses have traditionally been very theoretical, difficult to understand, (and boring), you will be captivated by the Mobius training methods, and you will enjoy our practical approach. You will take away skills that you can immediately apply to your job, and you will truly understand what you are doing.

You will come away from the course with a solid understanding of:

• How a well-designed program and the RCM approach will improve the OEE and the bottom line
• The condition monitoring technologies – via supplementary training
• How to select the correct measurement location and axis, and collect good, repeatable measurements
• What the Fmax, resolution, averaging and other single- channel and cross-channel analyzer settings mean, and how to select the optimum settings
• How to analyze vibration spectra, time waveform, envelope, and phase measurements
• How to diagnose a wide range of fault conditions
• How mass, stiffness and damping affects the natural frequency of a structure
• How to use phase readings, bump tests, impact tests, negative averaging, peak-hold averaging, transient, ODS, modal analysis to determine natural frequencies and visualize machine movement
• How to balance and align a machine, correct a resonance conditions, and employ isolation.

• If you are CAT II (or Level II) certified and are ready to take your career and responsibilities to the next step, and you wish to truly master vibration analysis, diagnosis and correction, then the CAT III Vibration Analysis course is ideal for you.
• You should have over 36 months of experience and a good understanding of fault diagnosis and spectrum analysis. (Note that you require 36 months experience to be certified). The RMS / Mobius Institute course and certification program follows the ISO 18436-2:2003 standard and the ASNT Recommended Practice SNT-TC-1A.
